连接副词既起连接作用，又在从句中作时间、地点、原因或方式状语。

?Thequestioniswhenhecanarriveatthehotel.

?WhatIwanttoknowishowyoucanpersuadehimtogo.

(4)其他连接词：because,asif/asthough等

?Thatsbecauseyoueattoomuch.

?Itlooksasifitisgoingtosnow.

;2使用表语从句时的注意事项

（1）当主语是表示“建议、命令、要求”的词（如suggestion,advice,order,request,demand等）

时，表语从句的谓语用“should+动词原形”，should可以省略。

·Hissuggestionisthatwe(should)staycalm.

（2）asif/asthough引导表语从句，表示与事实相反时要用虚拟语气。

·Itlooksasifsheweredrunk.（事实是她未醉）

·Itappearsasifhehadntmether.（事实是他见过她）;（3）表语从句的特殊句式

Thereasonwhy.….isthat.….……的原因是……

This/That/Itisbecause...这/那是因为……

This/That/Itiswhy...这/那就是……的原因
